Title: Semiconductor laser and manufacture thereof
Inventor: MITO IKUO
IPC: H01S5/00
Filed: 1986-01-24
Abstract: PURPOSE:To provide a semiconductor laser having excellent high speed response, ready manufacture and excellent reliability by burying a deep groove passing a second conductivity type current closure layer and a proton-implanted low density current block layer to laminate a first conductivity type buffer layer, an active layer and a second conductivity type clad layer on a substrate. CONSTITUTION:An n-type InP current closure layer 5 and a p-type InP current block layer 6 are continuously laminated on a (001) p-type InP substrate 1. The layer 6 is reduced largely in carrier density by implanting proton from the surface, but the density of the layer 5 is not almost varied. Then, a groove 30 which arrives at the substrate 1 is formed in (1<->0) direction, a p-type InP buffer layer 8, a non-doped InGaAsP active layer 9 and an n-type InP clad layer 10 are laminated, and the layers 8 and 9 are affected by the shape of the groove 30 to exhibit an uneven shape, but when the layer 10 is grown in thickness by 3mum, the groove 30 is buried. The substrate 1 side is polished until the entire thickness becomes 140mum.

Title: Slipper metal type universal coupling device
Inventor: ONISHI MASATOSHI
IPC: F16D3/26
Filed: 1994-02-08
Abstract: PURPOSE:To prevent the generation of a thrust force exerted on a work roll in linkage with rotation of a spindle. CONSTITUTION:Recessed parts 65a and 65b positioned in the slide surfaces of the nipping pieces 50a and 50b of a slipper metal 51 and closer to the base end part of a fork end part 48 are formed in the fork end part 48 of a coupling 49 on the roll side fixed to the other end part 43 of a work roll 45.

Title: Magnetic recording/reproducing device
Inventor: KAJIWARA MEGURI
IPC: G11B15/467
Filed: 1989-01-23
Abstract: PURPOSE:To prevent a tracking error which is caused at a new recording start point with a simple constitution by driving a magnetic tape in a reproduction state to secure an on-track state and starting a recording job in the case a recorded tape is recorded again. CONSTITUTION:An envelope detecting circuit 11 detects the presence or absence of a reproduction signal on a magnetic tape 2, and a synchronizing signal detecting circuit 8 detects a synchronizing signal. A tape drive means II controls the drive of the tape 2 based on the synchronizing signal at reproduction and then based on the phase reference regardless of the synchronizing signal at recording. A control means I drives once the tape 2 in a reproduction state when a recording job is started, and the circuit 11 detects the presence or absence of a reproduction. Then the reproduction state is immediately shifted to a recording state in the case the absence state in immediately shifted to a recording state in the case the absence of the reproduction signal is confirmed. While the recording state is secured after detection of the synchronizing signal in the case the presence of the reproduction signal is confirmed. For this purpose, the action mode of the means II is controlled. Thus it is possible to prevent a tracking error caused at a new recording start point with a simple constitution even in the case a recorded tape is recorded again.

Title: Discharge lamp lighting device for vehicle
Inventor: NAKAMURA KENJI
IPC: H05B41/38
Filed: 1993-01-05
Abstract: PURPOSE:To suppress the reduction in life by Na loss phenomenon and extend the life of a discharge lamp by setting the average lighting potential of the discharge lamp lower than the potential of a lighting fixture for housing it. CONSTITUTION:When a lighting switch is ON, a control circuit 3 starts operating to output a frequency (f) duty variable pulse signal to a switching element 2a, and also transmits a signal to a driver to drive switching elements 5a-d. The electromagnetic energy stored in a coil 2b in the ON-period of the element 2a is converted into an electrostatic energy, which is then accumulated in a capacitor 2d to show a minus voltage Va in a terminal (a) point. The circuit 3 transmits a signal to a high voltage pulse generating circuit 8b, when the voltage Va reaches a determined value, to carry a current to a discharge lamp 9 and start it. Thus, the voltages of electrodes 9a, 9b during lighting are lower than the voltage Va, and the discharge lamp 9 is lighted at an average lighting potential lower than the potential of a lighting fixture 10.
